Shopify customer account UI extension missing — profile or order history blocks not loading.

Several products can look like “something customer-facing is blank.” They do not share an editor. This page is only when a Shopify new customer accounts UI extension / app block is not loading or missing on profile, order history, or related account pages. Login / redirect / identity-provider failures are customer accounts login broken. Checkout editor / live checkout app blocks are checkout UI extension not loading. Admin embedded apps that white-screen after install are admin app blank after install. This page is only: customer account UI extension / blocks missing on new customer accounts.

Six ordinary reasons account UI blocks look missing: store still on classic customer accounts so account UI extensions never appear; app not installed or missing the customer-account extension target; blocks never added in the customer account editor for profile / order history; draft profile not published; app version outdated after Shopify account UI API changes; browser cache or a logged-out session so you never see the authenticated account surface. Walk them in that order. You already pay for Shopify Admin. You do not need another SaaS to prove why the block is absent.

Open Settings → Customer accounts. Capture: New customer accounts vs classic; any migration / preview notes. Then open the customer account editor (profile / order history / account pages) and list which app blocks the installed app offers. Hard-refresh Admin. Confirm the app is still installed and not pending an update.

Side-by-side with a logged-in customer account in a private window. Screenshot profile and order history before and after you add a block. If you cannot log in at all (redirect loop, Shop login / Multipass / identity), leave this page and use customer accounts login broken. If the missing block is on checkout (not the account area), open checkout UI extension not loading. If the blank screen is the admin app iframe after install, open admin app blank after install.

Align the New customer accounts → app install → account editor targets → publish → logged-in proof chain: switch to New customer accounts if you are still on classic and need account UI extensions; update or reinstall the app; add the UI extension / app blocks on profile and order history (and any other targets the app documents); publish the account configuration; hard-refresh a logged-in customer in a private window. Do not paste a checkout UI extension into the account editor and expect profile widgets to appear.

Retest with a real customer login (private window). If blocks load but login still loops, also walk customer accounts login broken. Related theme app extension blanks on the Online Store (not account UI): theme app extensions not appearing. Related new-accounts invite mail silence: customer account invite not sending.

Checklist: (1) screenshot Settings → Customer accounts showing New customer accounts, (2) confirm the app is installed and updated, (3) confirm customer account editor shows the app blocks for profile / order history, (4) add blocks and publish, (5) hard-refresh a logged-in customer account in a private window, (6) if only login / checkout UI / admin blank remains, switch playbooks.

Prove it: New customer accounts is on; account editor lists the extension; published profile / order history show the blocks for a logged-in customer; login / checkout UI / admin blank stay independent. If Admin editor looks correct but the customer never reaches the account surface, open customer accounts login broken.

Customer accounts login / redirect / Multipass / Shop login is customer accounts login broken. Checkout UI extension / checkout extensibility app block not loading is checkout UI extension not loading. Admin embedded app blank / white screen is admin app blank after install. Theme app blocks missing on the Online Store (not account UI) is theme app extensions not appearing. None of those finish a customer account UI extension bug where profile or order history blocks never appear after New customer accounts is on.

Finish prove New accounts / editor targets → add blocks + publish → logged-in proof first. Only then open the related playbook that matches the remaining symptom.

Stay DIY if you can spend one afternoon on the list above: prove New customer accounts and editor targets, add and publish the account UI blocks, and stop treating login / checkout UI / admin blank as the same bug. That is the whole playbook. No agency required. Short answers also live on the merchant FAQ.

Pay for help when the work is not the account UI toggle — it is connecting the stack you already have so lead capture is not dying in DMs, cart / ops exceptions land in a channel you already check, and the live store is one workflow instead of a spreadsheet plus a Slack bot you forgot. That is the Latch AI Ops install.

What $997 USD one-time buys: lead capture on the live store, ops alerts in a channel you already check, and a checkout-ready workflow. 72 hours after collaborator access, not after payment. One live Shopify store. Access plus a delivery thread. Store URL collected at checkout. Not a SaaS seat, not an upsell retainer, not a conversion guarantee, not a brand or theme job.

Other shops’ public ranges, not testimonials: a checkout / ops install typically runs $500–$2,500. A full ops consulting block typically runs $2,000–$5,000. $997 is the cheap end of that work, sold as a 72-hour install of three systems — not as an earnings number or uptime claim.

What it does not buy: more orders, automatic Plus eligibility, a custom account UI rewrite, or a case study. Latch AI Ops has not published customer proof because there are no customers yet. You are buying the install.
